The laboratory investigations in this manual are designed to demonstrate the theoretical principles set out in the book Fundamentals of Electronic Devices and Circuits, 5/e. A total of 43 laboratory investigations are offered, involving the construction and testing of the circuits discussed in the textbook. Each investigation can normally be completed within a two-hour period. The procedures contain some references to the textbook; however, all necessary circuit and connection diagrams are provided in the manual so that investigations can also be preformed without the textbook. * An introduction that briefly describes the investigation. * A list of required equipment and components. * Circuit diagrams and connection diagrams. * Step-by-step procedures. * A laboratory record sheet for recording data. * An analysis section for processing data.
